But were you an adult when the breach happened? The paper form says this: "If you were over the age of 18 on May 13, 2017, and wish to file a claim form, visit www.EquifaxBreachSettlement.com. Do not use this claim form."
It looks like, if your goals are a balance between receiving the settlement, privacy, and effort, the PDF (probably [2] if no minors were involved) is the way to go.
